Different types of distributed generation (DG) power plant have different impacts on distribution networks. This paper investigates the impact of optimal placement and sizing of different types of DG units in distribution networks with respect to power system losses and voltage profile. Three different types of DGs; solar photovoltaic, diesel generator and wind turbine are installed on a 30-bus 33kV radial distribution network. The analysis is conducted in power system software for Engineering (PSS/E) environment. The research used a two-step consolidated optimization novel technique with full Newton Raphson load flow algorithm combined with loss sensitivity factor to optimize the size and location of DG in the 33kV feeder distribution network. This optimization technique is evaluated using different types of distributed generators on the 30-bus, 33kV feeder distribution network. The obtained results show that different types of DG influence differently the distribution network and that their precise location and size are vital in reducing power losses and improving the voltage profile. The type 3 DG (wind) has the least potential for improving voltage profile as well as system power reduction of the distribution network. Hence this serves as a vital tool for system Engineers on the type of renewable energy source technology to be employed in integrating it to distribution power system.
